Memora nodosa is used in folk medicine as wounds healing and scabies treatment. This study evaluated the antimicrobial activity of ethanol extracts of leaves, stems, roots, fractions obtained from the roots and the essential oil obtained from the leaves and evaluated the chemical composition of essential oil from M. nodosa leaves. The best results were obtained with the hexane fraction (MIC of 0.39 mg/mL against M. roseus, M. luteus, B. cereus and C. albicans) and dichloromethane fraction (MIC of 0.39 mg/mL against S. epidermidis, M. luteus, M. roseus, B. cereus and B. subtilis) obtained from the roots. The essential oil presented MIC of 0.78 mg/mL to 1.56 mg/mL against Gram-positive bacteria and C. albicans and 1.56 mg/mL to 3.12 mg/mL against Gram-negative bacteria. The major component of essential oil was the benzaldehyde. The antimicrobial activity of this oil is probably mediated by the synergistic action of its constituents.
